Mutual Information based multi-modality registration methods are engaged in combination with automated vascular segmentation and image acquisition information for unified visualization of cardiac function and anatomy. Cardiac physiology is imaged using rapid MR methods (short-axis) to assess viability, perfusion, and myocardial wall-motion, while the coronary vasculature is derived from high-resolution CT Angiography (axial) data. An interactive environment to visualize Phased MR data and 3D MIP has been developed. An early embodiment of this integrated paradigm is prepared for clinical evaluation.
